Open Source Web Framework on Linux?

Hi everyone, we are embarking on a new journey here. Everyone, is, for the most part, are windows developers. We made the decision to go the linux/open source route for our new project (maybe?). We are trying to decide on a framework to go with and having a hard time coming up with a decision. One of the biggest requirements we are want is to have similar executing speed to c# & asp.net mvc. This requirement kind of throws out RoR & Django/python. We “prefer” a statically typed language but it’s not a hard set requirement. We dabbled with go & rust and enjoy both languages but I don’t think rust is ready for prime time. We also worry about the ecosystem with go. If you base your business off the language and then google decided it was a “toy” project and drops its resources (ala google reader). Sure its open source which is all fine and dandy just as long someone decides to pick it up (death of ironpython & ironruby). If the community was as vibrant as RoR/Django/Node we probably wouldn’t worry but it isn’t. The only option I see left is either java or a language based on the JVM. Any help would be appreciated.

Java seems to fit your needs, given how you have experience with C#. Play is a good framework to work with.

Yep. Java is pretty standard in enterprise because it's relatively fast, fairly easy to program, very portable, and has a mature community and ecosystem.

Grails.

I think you should reconsider Python. If it's fast enough for Instagram and Pinterest, it's probably fast enough for you :) Try Flask (http://flask.pocoo.org/).

If you go with Go after all, try Revel (http://robfig.github.io/revel/).
